quickmapr: Quickly Map and Explore Spatial Data

While analyzing geospatial data, easy visualization is often
needed that allows for quick plotting, and simple, but easy interactivity.
Additionally, visualizing geospatial data in projected coordinates is also
desirable. The 'quickmapr' package provides a simple method to visualize
'sp', 'sf' (via coercion to 'sp'), and 'raster' objects, allows for basic
zooming, panning, identifying,labeling, selecting, and measuring spatial
objects. Importantly, it does not require that the data be in geographic
coordinates.
